<2. PRECAUTIONS> 2-1 2. Precautions 2.1 Transportation and storage Before transporting the unit, it is recommended to fix the float with a card-board strip in the same way as when shipped from factory. Prevent foreign objects from entering the tube (e.g. by covering openings). To protect the unit and especially the tube’s interior from soiling, store it only at clean and dry locations 2.2 Installation Ambient temperature and humidity of the installation location must not exceed the specified ranges.
PAGE 17
<3. INSTALLATION> 3-1 3. Installation 3.1 Installation in the pipeline Be sure to remove the transport lock card-board strip from the measuring tube. Check that no cardboard remains in the tube. The RAMC flow rate meter must be installed in a vertical pipeline, in which the medium flows upwards. The vertical position has to be checked at the outer edge of the flanges. Bigger nominal diameters (DN80/DN100) require straight pipe sections of at least 5D in front and behind the RAMC.
PAGE 18
3-2 <3. INSTALLATION> 3.2 Wiring of electronic transmitter (-E, -H) and limit switches (/K_) Please regard the drawings on the following pages. On the rear of the RAMC are two cable glands for round cables with a diameter of 6 to 9 mm (not for Ex-d-type option /_F1). Unused glands must be closed with a blind plug M16x1.5. For wiring of RAMC with option /_F1 see chapter 10.9.2, 10.10.2, 10.13.2. Wires should not be bent directly at terminal screws. Do not expose wires to mechanical pressure.

<4. START OF OPERATION> 4-1 4. Start of operation 4.1 Hints on flow rate measurement The measured fluid should neither consist of a multi-phase mixture nor contain ferrite ingredients or large solid mass particles. The RAMC scale is adjusted to the state of operation/aggregation of the measured fluid by the manufacturer. If the state of operation changes, it might become necessary to establish a new scale.
PAGE 25
5-1 <5. LIMIT SWITCHES OPTION /K[]> 5. Limit switches (Option /K[]) The optional limit switches are available as maximum or minimum type switches. They are proximity switches according to EN 60947-5-6 (NAMUR). Maximal two switches can be installed. The option (/Wnn) includes the respective transmitter relay. These switches have been specified for hazardous area. However, the transmitter relay must be installed in safe area.
PAGE 27
<6. ELECTRONIC TRANSMITTER (-E)> 6-1 6. Electronic Transmitter (-E) 6.1 Operation principle The position of the float is magnetically transferred to a magnetic follow up system. The position angle of this magnetic rocker is detected by magnet sensors. A micro controller determines the angle by means of a combining reference value table in the memory and calculates the flow rate by the angle with calibration and operation parameters the calibration EEPROM.

6-4 <6. ELECTRONIC TRANSMITTER (-E)> 6.2.1 Selection of indication function (F11) The function F11 selects the display’s indication function. The following indications can be set: flow rate, totalizer, % value or temperature. At the factory the display is preset to totalizer indication.
PAGE 31
6-5 <6. ELECTRONIC TRANSMITTER (-E)> 6.2.2 Setting the unit (F12 / F13) When ordering the transmitter two sets of metering units are available. It is not possible to switch between them. These two sets comprise the following metering units: European unit set, Standard Standard Flow rate unit Unit Menu / Index m³ l Nm³ -1 -2 -3 Nl t kg scf -4 -5 -6 -7 --- Cubic meter Liter Norm cubic meter (0°C; 1 Atm.abs = 1.013 bar Norm Liter Ton Kilogram Standard cubic feet (21°C; 1Atm.abs = 1.
PAGE 32
6-6 <6. ELECTRONIC TRANSMITTER (-E)> With functions F12 and F13, the measuring unit for displayed value is selected. F12 selects volume and mass units, while F13 sets the corresponding time unit. When selecting the indication function “totalizer” the set time unit is not taken into account and only the selected mass or volume unit is effective. When choosing the “%” indication F12 and F13 have no effect.
PAGE 33
6-7 <6. ELECTRONIC TRANSMITTER (-E)> 6.2.3 Totalizer reset (F14) Function F14 resets the totalizer to zero. The counter reset is performed as follows: Description Selection Key Indication Change to setting mode Enter Display mode F1- Setting mode Enter 3x→ Enter F11 F14 F14 -1 Enter F14 Selection Reset ↑ ↑ Back to display mode Note: F1Display mode If you press “↑" instead of “Enter”, you can return from the selected point to the previous menu without activating the displayed parameter.
PAGE 34
6-8 <6. ELECTRONIC TRANSMITTER (-E)> 6.2.5 Setting of damping (F2-) Function F21 allows damping the output with a certain time constant (63% value). Normally the time constant is set to 1 sec.
PAGE 35
6-9 <6. ELECTRONIC TRANSMITTER (-E)> An adjusting step corresponds to 20 µA. The complete adjusting range is ± 0.62 mA (31 steps). If the adjusting range does not suffice, change to display F32 or F33 by pressing ENTER when display shows F32 31 or F33 31, press ENTER again and continue adjusting at F32 00 or F33 00. 3 wire connection: At this the ranges 0-20 mA and 4-20 mA are possible.
PAGE 36
6-10 <6. ELECTRONIC TRANSMITTER (-E)> 6.2.7.1 General The volume totalizer function in the electronic transmitter is available with a potential free pulse contact. The connection is supported only at 4-wire-units on the power supply at pins 6, 7. The pulse output is activated and selected by function F34 in the menu structure. Two different pulse rates can be selected. The lower pulse rate (higher solution) corresponds to the last (least significant) digit of the totalizer.
PAGE 37
<6. ELECTRONIC TRANSMITTER (-E)> 6-11 6.2.7.4 Calculation of pulse rate Concerning the final flow-value (Qmax ), which was declared in the customers order, the pulse rate is calculated in factory and is written onto the sheet ´Data of Pulse Output (Option /CP)´, which is included. This value can be transferred to a blank label of the also included sheet with unit-stickers and then fixed on the scale. After changing the flow rate unit with F12 the pulse rate must be recalculated.
PAGE 38
6-12 <6. ELECTRONIC TRANSMITTER (-E)> 6.2.8 Error messages (F4-) If the 8 bars beneath the digits start flashing, an error has occurred in the measuring transmitter/current output. Since the pointer indication is independent from the electric measuring transmitter, it may show the correct measuring value even if the transmitter is defective. Function F41 allows checking of assigned error codes.
PAGE 39
6-13 <6. ELECTRONIC TRANSMITTER (-E)> 6.2.9 Manual adjustment (F5-) During manufacturers adjustment and calibration process the relation between flow rate with water (or with air) and float position (indicated as angle on the mm-scale) is determined. Based on the properties of the customers fluid at expected operating conditions the flow scale and the corresponding EEPROM is then calculated.
PAGE 40
6-14 <6.
PAGE 41
<6. ELECTRONIC TRANSMITTER (-E)> 6-15 For the manual adjustment procedure according to the two cases described the following remarks have to be taken into account: • • • • • • • After manual adjustment the flow-scale of the indicator is no longer valid. The display will only indicate in % of the new flow range. Switching of units is impossible. The indicator can be always resetted to the original adjustment according to manufacturers calibration at any time.
PAGE 42
6-16 <6. ELECTRONIC TRANSMITTER (-E)> 6.2.10 Revision indication (F61/F62) Functions F61 and F62 enable the indication of revision states for hardware, software of calibration EEPROM and internal EEPROM.
PAGE 43
6-17 <6. ELECTRONIC TRANSMITTER (-E)> 6.2.12 Switching between standard / Indicator on extension (F64) F64 allows switching between the standard calibration table and a calibration table of the remote version (option /A2 for high temperatures). The adjustment has to be performed according to the RAMC type (MS code).
PAGE 44
6-18 <6. ELECTRONIC TRANSMITTER (-E)> 6.2.14 Float blocking indication (F7-) 6.2.14.1 Function Float Pulsating movements of the flow medium (gasses, liquids) lead to fluctuations of the float and with that to fluctuations of the tap system/pointer. Therefore the electrical measuring signal permanently changes and with that the display value and the output current value. The fluctuations can be reduced with the help of the damping function “F21”.
PAGE 45
<6. ELECTRONIC TRANSMITTER (-E)> 6-19 Autozero with flow The Autozero function can be carried out also under flow, if the flow cannot be switched off. To this the following expiry is recommended: - Plant in operation (measuring tube filled with medium) - Move flow to constant value (preferably between 10% and 40%) - Fix pointer on the oriented scale factor with adhesive tapes or underlayed paper stripe - Start Autozero function by menu. - Check Autozero value after approx. 80 seconds.
PAGE 46
6-20 <6. ELECTRONIC TRANSMITTER (-E)> 6.2.14.3 Unsuitable applications It is possible, that the Float-Blocking-Indication- Function does not work satisfactorily. This can be caused with different factors which are explained briefly here. In these cases the function of the Float-Blocking-Indication is not suitable for the respective application and it should be turned off.

<7. HART-COMMUNICATION> 7-1 7. HART® - Communication 7.1 General RAMC with indication unit type -H have, additional to the current output, the possibility for HART®Communication. Also without HART®- Communication the units are fully able to work. The HART®Communication does not influence the current output, except in Multidrop-Mode (see below). There exists no difference between the not-Ex and the Ex versions. For use in the hazardous area a HART®-able transmitter power supply is required.
